CARBURETER.

Specification of Letters Patent.

Application filed October 12, 1909. Serial No. 522,282.

To all whom it may concern:

Be it known that I, FREDERIC STANTON PERRIN, a citizen of the United States, and a resident of the city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Carburetors for Internal- Comb'u'stion Engines, of which the following is'a specification. I

' My invention relates. to improvements in carbureters for internal combustion engines, and the objects of my improvements are, first, to transform volatile fluids, such as gasolene, into a gaseous state; second, to atomize non-volatile liquids, such as kerosene, and transform them into an aerlform elastic fluid; and, third, to increase or decrease, at will, the supply of the fluid to be transformed. I attain these objects by the mechanism illustrated in the accompanying drawing, in which- Figure 1 is a vertical section of the entire carbureter; Figs. 2, 3 and 4 are views of a movable plate resting upon the nozzle at diflerent positions, and Fig. 5 is a detail of the nozzl Similar numerals refer to similar parts throughout the several views.

In Fig. 1 the numeral 1 represents a fluid reservoir having a float 3, operating the valve 4, in the supply pipe 5, to prevent the over-flowin of the fluid; 2 is the gas chamher connecting with the passage 18, leading to the engine cylinder and an auxiliary air chamber 20, which is closed by the valve 15; 8 represents a nozzle having an opening 7, connecting with the duct 6, leading from the reservoir 1; 9 is a plate resting upon the nozzle 8, with an aperture 16, shown in Figs. 2, 3 and 4, to which plate is attached a U shaped rod 11; 13 is a prolongation of 11, attached to the lever 14; 12 is the air intake chamber through which the main air enters; and 17 is the inlet through which the auxiliary air enters the valve chamber 20.

In Figs. 2, 3, 4 and 5 the numeral 10 represents a narrow longitudinal vent in the nozzle 8. The broken line 19 represents the level of the fluid maintained b the float 3, in the reservoir 1, by means 0 the valve 4.

The operation of the carbureter is as follows: Fluid from a supply tank (not shown in the drawing) enters the opening 5, and flows into the reservoir 1, until the float 3 rises and closes the valve 4, when its level reaches the broken line 19. This fluid passes through the duct 6, up through the opening 7, in the nozzle 8, to a short distance below the nozzle vent 10, as shown by the line 19. The engine cylinder (not shown) is connected with the passage 18 by means of a tube, in such a manner that the moving of the piston, within its cylinder, draws air through the main inlet 12, over the nozzle vent 10, through the aperture 16, in the plate 9. This plate may fit closely against the wall of the inlet chamber 12, and rotates adjacent and preferably upon the nozzle 8,

practically closing the passage through chamber12 except at the aperture 16 of plate 9. As this air passes over the nozzle vent 10. When the fluid rises above the vent, the air picks it up and transforms it into a fine spray, which is carried into the cylinder in a gaseous state, if the fluid is volatile, or an aeriform elastic fluid, if the fluid is non-volatile.

The plate 9 has the aperture 16 at its center a little-shorter than the length of the nozzle head, to prevent the nozzle from passing through the aperture, and considerably wider than the width of the nozzle head. This plate is movable upon the nozzle by means of the lever 14, rod 13, and U shaped rod 11. Fig. 4 shows the aperture 16 at right angles with the vent 10, exposing a small portion of the vent; Fig. 2 shows the plate 9 moved to an angle of forty-five degrees, exposing a greater portion of the vent; and Fig. 3 shows the plate moved to a position placing the aperture parallel with the vent, and exposing its full length. It will be seen, by this means, I am enabled to expose any portion of the vent to the incoming air, and allow the air to draw up fluid according to the portion of the vent exposed by the aperture 10. The bottom of the plate 9 rests upon the nozzle and closes the vent 10 at all points except opposite the aperture 16. j v

The auxiliary air valve 15 is set, by the tension upon its spring, to open by the suction of the piston and take in suflicient air to mix with the fluid spray and form a proper explosive mixture in the cylinder.

-With the nozzle shown in Fig. 5 the longitudinal vent 10 is gradually increased or decreased by moving the aperture 16 and lengthening or shortening the exposed portion of the vent;

The supply of fluid may be increased or decreased at will by simply changing the 1. In a carbureter having an air chamber open at'opposite ends, a nozzle, leading from a fluid reservoir, formed at its outlet with a narrow longitudinal vent, said nozzle being located between the open ends of said chamber, a plate fitted in said chamber upon the nozzle and rotative thereon in the chamber, saidplate having a perforation longer than wide and wider than the top of the nozzle.

2. In a carbureter, a nozzle, leading from a fluid reservoir, formed at its outlet with a narrowlongit-udinal vent; and a plate having a perforation wider than the top of the nozzle adapted to move upon the nozzle in a manner to close the vent at all points except opposite the perforation, the latter being arranged to permit the flow of air therethrough, substantially as described.

3. A carbureter comprising a nozzle, leading from a fluid reservoir, formed at its outlet with a narrow vent, and a plate having a central perforation wider than the top of the nozzle adjacent and coacting with said vent to control the flow of fluid from said vent, said perforationbeing arranged to permit the flow of air therethrough past the county of New York and State of New York this 11th dayof October, A. D. 1909.
